Add api/ with a FastAPI app that imports the bundled NestQuest core
(Feature 15) WITHOUT importing homeassistant: api/nestquest_core.py
bootstraps the integration directory onto sys.path and imports core as
a top-level package, so custom_components/nestquest/__init__.py (which
imports HA) never executes. This transitional coupling is encapsulated
in one documented helper to revisit in Feature 18.
The app reads NESTQUEST_DB_PATH (env var, documented temp default),
opens+migrates the SQLite database in a FastAPI lifespan, and serves
GET /health (200, status ok + resolved db_path) and the OpenAPI doc at
/docs and /openapi.json. Tests start the app with httpx against the
ASGI app and assert all three; a subprocess test proves the app
imports core without importing homeassistant or registering
custom_components.
Add fastapi, uvicorn, httpx to the dev dependency group; uv lock.
Suite green at 1581 (1576 baseline + 5 new API tests).
Iterates present children from the Feature 10 presence sensors, lists
what each owes today from the remaining sensor, omits absent children
entirely. Blueprint inputs (time, notify service, send toggle); the
notify target is the household's choice, never hard-coded. PyYAML and
Jinja2 join the dev-only dependencies for blueprint template tests.
